Improvement in putting up baking-powders



netos GEORGE F. WILSON, OF PROVIDENCE, RHODE ISLAND.

IMPROVEMENT in Pfu'rrlne UP eAKlnev- Powosue Specication forming part ot' Letters Patent No. 118,768, dated September 5, 1871.

To all whom; it may concern:

Be it 'known that I, GEORGE F. WILSON, of Providence, in the county of Providence und State of Rhode Island, have invented a new and useful Mode of Putting up Baking-Powders and other articles of a like character, of which the following;` is a specification:

If the several ingredients which enter into the composition of what are known as baking-powders be kept separate until the time when they are required to'he mixed for actual use, the powders will preserve their quality and eiiieiency a much longerI time thanv it' they were packed and mixed together in the same can. My invention is intended to keep the several ingredients of these powders separate, and it is applicable not only to bakingpowders, so called, but to other articles or compounds, the ingredients oi' which should be kept separate. until required for use. The ipvention consists in the putting upin one can or case ot' the powder or other article in such manner that each ingredient of the same shall occupy a compartment or space in the can separate and isolated from the other. It further consists in the use for this purpose of a sheet-metal can divided into two partseach closed at the bottom to form a, chamber for the reception of' one of the ingredients ofthe powder, the upper part being provided with a removable cover, and fitting' and forming the cover of the lower part.\`

The manner 'In which my invention is or may be carried int-o effect will be readily understood by reference to the accompanying drawing, in which- Figure l represents, in perspective, the sev eral` parts of a can which I preter'to use in carrying my invention into eit'ect. Fig. 2 is a vcrtical central section ofthe can, with all the parts shown sel telyin Eig. l fitted together. The can is divided into two parts, A B, each provided with a bottom, a b, for the purpose above stated, the one part having` the saine ex- .terior form 'as the other, so that when the two are put together they may appear to be one and the sume can.

The capacity ot' the chambers is regulated by the quantity of' the powder or other ingredient they are to contain.

ln the present case the upper part A is in- .ded to contain the cream-tartar or acid, and

the lower part l' the soda, used in making baking-powders, and the parts are, therefore, ot,l such size us to hold the proper proportion ot' each required to form the powders. The upper port A lits in or upon or over the topof the lower partv B and forms the cover ofthe same, as seen in Fig. 2, and it is provided itself with a cover, C, which iits it, as shown in the figure referred to. rlhe different ingredients et' thel lpowder can be thus kept separate and isolated from each other, and yet they are put up in a can not di'ering in extreme appearancefrom an ordinary can, and they may be put in the market and-sold like ordinary baking-powders.U 0i"4 course, if there are more than two-ingredients which enter into the composition of the powder or otherpreparation intended to be thus put up the eanmust have a corresponding,` number of compartnients-that is to say, it may have one bottom part, E, and two or more upper parts, A, the upper one fitting and formingl the cover ofthe next lower onesandthetop one closed by a cover, C. l In lieu of acari made as shown in the drawz ing, the bodyl B of the. can might be opened at both ends with a horihqntal partition ,dividing it into two parts, ea'cproportionate in size to the quantity of powder to be putin it, and then the two ends might ca ch be closed by'covers, so that by turning one or the other of the endsup and removing its' cover access might be had to either of the ingredients without ,disturbing the other.I And it is manifest that the can may be made in other ways, so that the ingredients shall beheld each separate und isolated from the'othcrs, and so that the chamber containing one may be opened without disturbing, the other. l

Having now described my invention and the manner in which the same is or may be carried into eftect, what l claim, and desire to secure by n csses.
